X-ray pump/X-ray probe applications are made possible at X-ray Free Electron Laser (XFEL) facilities by generating two X-ray pulses with different wavelengths and controllable temporal delay. In order to enable this capability at the European XFEL, an upgrade project to equip the soft X-ray SASE3 beamline with a magnetic chicane is underway. In the present paper we describe the status of the project, its scientific focus and expected performance, including start-to-end simulations of the photon beam transport up to the sample, as well as recent experimental results demonstrating two-color lasing at photon energies of 805 eV + 835 eV and 910 eV + 950 eV. Additionally, we discuss methods to analyze the spectral properties and the intensity of the generated radiation to provide on-line diagnostics for future user experiments.

Near Future

After having reached the status of user facilities in the infrared, Free Electron Laser (FEL) oscillators are becoming interesting light sources for scientific research also in the UV/VUV wavelength region. Thanks to continuous advances in accelerator and mirror technology, it has been possible to reach with tunability energies which are hardly accessible with conventional lasers (the European FEL project at Elettra recently lased below 190 nm), with the realistic perspective of reaching even shorter wavelengths in the near future. Thanks to their unique properties, such as tunability, full coherence, high intensity, spectral and temporal stability, they offer new opportunities for many kinds of spectroscopy: in particular, storage ring FELs are ideal sources for pump–probe experiments in conjunction with synchrotron radiation, as demonstrated by a series of studies of the nonequilibrium space charge distribution at photoexcited Si surfaces and interfaces performed at SuperACO. Besides, especially when operated at shorter wavelengths, FEL oscillators are very attractive also for one-photon experiments requiring high power and full tunability. We describe here the properties of the sources, and provide an overview of the experiments that have been performed and that are planned to exploit the new opportunities they offer.

Under Construction

The status of the European X-ray Free-Electron Laser (European XFEL), under construction near Hamburg, Germany, is described. The start of operations of the LCLS at SLAC and of SACLA in Japan has already produced impressive scientific results. The European XFEL facility is powered by a 17.5 GeV superconducting linear accelerator that, compared to these two operating facilities, will generate two orders of magnitude more pulses per second, up to 27 000. It can therefore support modes of operation switching the beam up to 30 times per second among three different experiments, providing each of them with thousands of pulses per second. The scientific possibilities opened up by these capabilities are briefly described, together with the current instrumental developments (in optics, detectors, lasers, etc.) that are necessary to implement this program.
